Description

Screen content enlargement display method and terminal

The present invention relates to the field of communications technologies, and in particular, to a screen content enlargement display method and terminal. Background technique

With the development of mobile communication technologies, the processing capabilities of mobile terminals are gradually enhanced, allowing information such as web page images or documents to be displayed on the display screen.

At present, the screens of mobile terminals generally use resistive screens and capacitive screens that support touch technology, and most of them are capacitive screen applications. The existing capacitive screen supports multi-touch technology, allowing users to use their fingers to control the display of the terminal screen, such as zooming in, zooming out or moving.

Multi-touch technology is based on the combination of human-computer interaction technology and hardware devices. It can be touched by a touch screen (screen, desktop or wall) or without traditional input devices (such as mouse, keyboard, etc.). The control board simultaneously accepts computer-based human-computer interaction operations based on multiple points on the screen. Users can make a single touch with both hands, or touch the screen with different gestures such as click, double click, pan, press, scroll and rotate, so that users can better understand the relevant features of the object (text, video, picture) , satellite, 3D simulation and other information).

However, due to the limited size of the display screen of the mobile terminal, visual information can only be displayed as a smaller image with a higher resolution. When browsing the webpage, the end user needs to frequently zoom in, zoom out, or scroll up and down to properly view the webpage or document information on the screen. When zooming in, zooming out, and moving, the target webpage recalculates the layout to fit the entire screen. The refresh time of the entire screen is longer. If the content of the webpage is more complicated, the refresh rate of the screen is slower. Therefore, frequent full-screen refreshes can generate a large amount of user waiting time, which seriously consumes the user's effective reading time.

In addition, when the user performs zooming and moving operations, the user is also inconvenienced, and the user is If you want to see the webpage, you need to enlarge the webpage. However, if the user needs to view other parts of the webpage, you need to move the webpage. If the previous webpage magnification is larger, the user needs to move more frequently. The user needs to narrow down the webpage to determine the location of the next webpage content. However, if the scale of the reduction is not appropriate, the user may not be able to see the webpage content, and the user has to enlarge the webpage again, so the webpage is frequently zoomed and moved. , making it impossible for users to browse the web efficiently, and seriously reducing the efficiency of users' discovery of browsing points of interest.

The solution of the embodiment of the present invention is mainly: setting a screen content enlargement function of the terminal, the user selects the content to be enlarged from the original screen through the finder frame, and the image display screen enlarges the content of the finder frame, and the user can drag the finder frame And the imaging screen can be arbitrarily moved on the screen, and the size of the finder frame and the imaging screen can be arbitrarily changed by single or multi-touch; at the same time, the enlarged content can be operated in the imaging screen, such as clicking on a webpage link, click feeling Interested icons, calling out applications, and selecting and copying texts are convenient for users to watch and read to enhance the user experience.

The terminal of the present invention can be any electronic screen display device having a touch screen function.

Taking a touch mobile phone as an example, when a traditional touch mobile phone user browses a webpage, in order to discover the browsing interest point, the webpage needs to be frequently zoomed and moved. Zooming in and moving During operation, the target webpage will recalculate the layout to adapt to the entire screen, so that the refresh time of the entire screen is longer, the more complex the content of the webpage, the slower the refresh rate of the screen, and the frequent full-screen refresh will generate a large amount of user waiting time. , seriously consuming the user's effective reading time. In the traditional mode, the user's zoom operation conflicts with the mobile operation. The user needs to enlarge the webpage in order to see the webpage. However, after the webpage is enlarged, the user needs to move the webpage to find the next interest point in order to view other parts of the webpage, if zoomed in The larger the multiple, the more frequently the user needs to move; to speed up the discovery of the next point of interest, the user needs to zoom out to help quickly determine the location of the next point of interest, but if the reduction is not appropriate , the user will not be able to see the content of the webpage, causing the user to not find the next point of interest efficiently, and the user has to enlarge the webpage again.

Therefore, frequent zooming and moving of the webpage occupies the effective browsing time of the user, and the efficiency of the user to discover the browsing interest point is seriously reduced. The bigger the page, the more complex it is, the worse the user experience.

In addition, although the magnifying glass tool carried by the Windows operating system can partially enlarge the screen content, the magnification is a fixed number of preset levels, cannot be steplessly adjusted, and the capturing area of the magnifying glass (equivalent to the present invention) The size of the framing frame is adjusted indirectly by adjusting the magnifying glass frame (equivalent to the imaging screen of the present invention). The area of the capture area is automatically pushed by Windows according to the size of the imaging screen and the currently set magnification, and the finder frame is invisible to the user, so the user cannot intuitively feel the size, shape, and the whole of the finder frame. The relative positional relationship of the screens makes the user's targetness when moving the magnifying glass to the position of the screen content of interest deteriorates.

At the same time, since the outline of the original screen content blocked by the imaging screen behind the imaging screen cannot be displayed, the relative positional relationship between the finder frame and the imaging screen relative to the entire area of the original content of the screen is lost, and the overall sense of viewing of the original full-screen content of the screen is split. Because the overall feeling of the original full-screen content of the screen is split, the user cannot see the corresponding content at the same time while seeing the enlarged content area. The relative relationship between the capture area and the outline of the original content of the screen covered by the magnifying glass and the overall screen makes it difficult for the user to quickly move the magnifying glass directly to the screen content module area to be observed. Especially for complex multi-frame webpages, the user needs to repeatedly adjust the magnification and the size of the imaging screen, so that the content in the enlarged webpage sub-frame to be viewed is completely displayed on the imaging screen, so that the user is watching this. User experience is seriously degraded when class-based web pages.

Based on this, the present invention improves the prior art, and allows the user to freely enlarge a part of the content of the webpage on the screen without changing the overall information of the webpage, so that the user can conveniently view the webpage and speed up the user's discovery of the interest points in the webpage. The speed of the user greatly enhances the viewing experience of the user using the mobile terminal.

Specifically, as shown in FIG. 1, an embodiment of the present invention provides a method for displaying a screen content, including:

In step S101, the terminal selects the display area to be enlarged from the original screen through the finder frame. In order to realize the enlarged display of the content of the selected area in the screen, the terminal of the embodiment is provided with a magnifying glass system, and the magnifying glass system includes a framing frame and an imaging screen, and the framing The frame and imaging screen are set on the same screen on the terminal screen. The finder frame is a framing and position reference of the loupe system, and is used to cover an area of interest in the original content of the screen, that is, an area defined by the finder frame is an area where the original content of the terminal screen is selected, and the user can pass the finder frame by himself. The area to be enlarged and displayed is selected from the original content of the terminal screen; the imaging screen is used to enlarge the content of the area to be enlarged and displayed in the original content of the terminal screen selected by the finder frame.

The size of the imaging screen and the relative position of the imaging screen and the finder frame are automatically calculated and adjusted by the magnifying glass system according to a preset magnification, which is used to ensure that the content in the finder frame is enlarged at the current magnification and can be completely displayed in the imaging. On-screen, and to ensure the viewing integrity of the imaging screen, that is, to ensure that the area of the imaging screen is always inside the boundary of the terminal screen.

When the magnifying glass is initially started, the magnifying glass system automatically calculates a suitable initial magnification display number according to the display resolution of the existing screen content, and the screen with higher resolution can be compared. Set a higher initial magnification display multiple.

The size of the finder frame when the magnifying glass is initially started is the size specified by the magnifying glass system by default, and the position of the framing frame is the default position specified by the magnifying glass system.

The size and position of the imaging screen are set according to the size and position of the finder frame and the predetermined magnification. For example, the central coordinate position of the imaging screen in the screen can be set according to the central coordinate position of the finder frame in the screen and the predetermined magnification.

As shown in FIG. 2, FIG. 2 is a schematic diagram showing the default relative positional relationship between the finder frame and the imaging screen in this embodiment. A magnifying glass tool enable control button is provided on the terminal screen, and the magnifying glass function can be turned on and off by this button.

When the magnifying glass tool is opened, the default position of the imaging screen relative to the framing frame is based on the center position of the framing frame, and the display position of the imaging screen is calculated according to the currently set horizontal and magnification. For example, the origin of the current frame is (XI, Y1) and the magnification is Z. The coordinates of the default center position of the imaging screen are (X1 *Z, Y1 *Z ).

In addition, the relative relationship between the magnifying glass's imaging screen and the viewfinder can be flexibly set by the user. The user can use the linkage control button (shown in FIG. 2) set on the terminal screen of the magnifying glass system to set the imaging screen to move simultaneously with the finder frame, that is, when the user moves the finder frame, the imaging screen and the framing frame move at the same time. Or when the user moves the imaging screen, the finder frame moves at the same time as the imaging screen; or the imaging screen does not move, stays at a fixed position on the screen designated by the user, and moves the finder frame separately. At the same time, you can also set the magnifying glass moving handle on the screen.

As shown in FIG. 3, FIG. 3 is a schematic diagram of the movement of the magnifying glass in this embodiment. The grid area in Figure 3 (except for the frame of the viewfinder and the magnifying glass) is the focus area of the magnifying glass. When the user touches the area and does not release, the magnifying glass enters the movable state, and the user can drag the magnifying glass to the screen. On any location.

As shown in FIG. 4, FIG. 4 is a schematic view showing the position of the imaging screen in the embodiment. When the user presses the linkage control button, the position of the imaging screen will be fixed at the current position and cannot be moved. The finder frame is still Can be moved at will.

When the finder frame moves at the same time as the imaging screen, the finder frame may be located inside the imaging screen or outside the imaging screen; or intersect with the border of the imaging screen.

When the user sets the imaging screen to move at the same time as the framing frame, the magnifying glass system calculates the appropriate position of the imaging screen on the screen in real time to ensure that the imaging screen is completely displayed on the terminal screen. For example, when the user moves the finder frame close to the screen boundary, the imaging screen in the default position relationship will also exceed the screen boundary. At this time, the system will calculate to ensure that the area of the imaging screen falls within the screen range visible to the user.

As shown in FIG. 5 and FIG. 6, FIG. 5 and FIG. 6 are schematic diagrams showing the adaptive display of the position of the imaging screen when the finder frame approaches the edge or the edge of the screen in the embodiment. When the finder frame is close to the edge or corner of the screen, if the imaging screen is displayed in the default relative positional relationship with the finder frame, part of the imaging screen may exceed the screen boundary, and the magnifying glass system will calculate the appropriate image on the terminal screen. The display position is such that the complete imaging screen area falls within the user-visible screen range. For example, the upper left corner of the screen is the origin of the coordinate system (0, 0), and the lower right corner of the screen is the boundary of the coordinate system (X0, Y0). The width of the current frame is W and the height is H. The coordinate position of the center of the current frame is (XI, Y1), and the magnification is Z. The default center position of the imaging screen is (X1+W/2*Z, Y1+H/2*Z), ^ X1+W /2*Z>X0 il<0, indicating that the imaging screen is out of the display range of the current screen in the horizontal direction, the magnifying glass will be translated to the new X coordinate position in the X (horizontal) direction, and X1+W/2*Z< X0 or >0; If Y1+H/2*Z>Y0 or <0, indicating that the imaging screen is out of the display range of the current screen in the vertical direction, the magnifying glass will be translated in the Y (vertical) direction to the new Y coordinate position. , and make Y1+H/2*Z<Y0 or >0.

In step S102, the original display content in the display area to be enlarged selected by the finder frame is displayed on the imaging screen at a predetermined enlargement ratio, and the imaging screen and the finder frame are disposed on the same screen in the original screen.

The original display content in the display area to be enlarged selected by the finder frame is displayed in the imaging screen at a predetermined magnification ratio (magnification), and the predetermined magnification is automatically enlarged by the magnifying glass system according to the existing screen content display resolution. Multiple, the higher the contrast resolution On the screen, you can set a higher initial magnification display multiple. In addition, the predetermined magnification may be configured by the user and stored in the terminal as needed. In actual operation, the user may select to call the local existing amplification ratio configuration, and the imaging screen performs enlarged display according to the amplification ratio.

When the magnifying glass system displays the magnified content in the imaging screen, it can be displayed in a pixel-extended form, or in an enlarged form of the extracted character font.

The following two methods are elaborated below:

As shown in FIG. 7, if the pixel is displayed in the form of pixel enlargement, the step S102 includes the step of displaying the original display content in the display area to be enlarged selected by the finder frame in the imaging screen at a predetermined enlargement ratio, including:

Step S1021, the pixel points in the finder frame are enlarged by a predetermined amplification ratio by using an interpolation algorithm, and the position coordinates of the enlarged pixel points in the imaging screen are calculated;

Step S1022: Display the enlarged pixel points at corresponding coordinate positions in the imaging screen.

Specifically, the method is to enlarge the original image in the finder frame by pixel level and display it in the imaging screen. The pixel value of each enlarged target pixel on the imaging screen is calculated by the pixel value of the original pixel in the finder frame according to a predetermined interpolation and amplification algorithm, and then the enlarged target pixel point is displayed one by one on the imaging screen. The amplification algorithm in this embodiment specifically uses a quadratic interpolation algorithm, and the principle is as follows:

The quadratic interpolation algorithm described herein is: for the pixel value corresponding to the enlarged target pixel point on the imaging screen, the coordinate corresponding to the ideal pixel coordinate calculated by the coordinate mapping algorithm is generally a floating point number instead of an integer. The pixel values of the adjacent nearest four integer coordinate pixel points around the floating point coordinate are taken as input parameters, and the pixel values of the four pixel points correspond to different weights, if the horizontal coordinate of the pixel point is away from the level of the ideal coordinate The closer the coordinate distance is, the larger the horizontal weight value is selected. If the vertical coordinate of the pixel point is closer to the vertical coordinate distance of the ideal coordinate, the larger vertical weight value is selected, and then the pixels of the four pixel points are selected. Value and corresponding level And the vertical direction weight value is used as an input parameter to calculate the pixel value of the target pixel of the imaging screen. The specific algorithm is as follows:

As shown in FIG. 8, FIG. 8 is an enlarged display method of the content of the finder frame on the imaging screen in the embodiment. Set the screen coordinates corresponding to the original pixel points in the frame as (i, j), i and j are integers, and the screen coordinates corresponding to the enlarged target pixels on the imaging screen are (X, y), X and y. For integers, (m, n) is the pixel position (X, y) on the imaging screen. The ideal pixel position on the framing frame obtained by the coordinate mapping function of the imaging screen and the framing frame. m and n may be integers or possible. The coordinate mapping function of the decimal, imaging screen and framing frame is f (x, y). The pixel value of the enlarged target pixel on the imaging screen is T ( X, y ), and the pixel value of the original pixel on the finder frame is S ( X, y).

Here, the lower left corner of the screen is the reference coordinate system origin, and the center of the imaging screen is located at the upper right of the center of the framing frame. Then, ( m, n ) = f ( X, y) = ( χ / ρ - ρθ, y / h - hO ), p is the magnification in the horizontal direction, h is the magnification in the vertical direction, ρθ is the pixel distance difference between the center point of the framing frame and the center point of the imaging screen in the horizontal direction, h0 is the center point of the framing frame and the center of the imaging screen The pixel point distance difference in the vertical direction. For the target pixel point (X, y) on any imaging screen, the floating point coordinates of the corresponding ideal pixel point in the finder frame can be calculated by the above coordinate system mapping relationship as (m, n) = (i+u , j+v), where i, j are integers, u, v are floating point numbers in the interval [0, 1], and the pixel value T (X, y) of the enlarged target pixel on the imaging screen can be framing The pixel values of the four original pixel points of the coordinates of (i, j), (i+1, j), (i, j+1 ), (i+1, j+1 ) are jointly determined, and the horizontal direction is set. The weight ratio coefficient is hwO, hwl, and the weight ratio coefficient in the vertical direction is vwO, vwl, and the pixel value of the enlarged target pixel on the imaging screen is T (X, y) = hw0*vw0*S (i, j )+hw0*vwl*S( i, j+1 ) +hwl*vw0*S ( i+1 , j )+hwl*vwl*S (i+1, j+1 ). If hw0=lu, hwl=u, vw0=lv, vwl=v, and edge P (T, x, y) = ( 1-u) * ( 1-v) *S (i, j ) + ( 1-u) *v*S ( i, j+1 ) +u* ( 1-v) *S (i+1, j ) +u*v*S (i+1, j+l ). . As shown in FIG. 9, if the image is displayed in an enlarged form by using the extracted character font, the step S102 includes the step of displaying the original display content in the display area to be enlarged selected by the finder frame at a predetermined enlargement ratio in the imaging screen.

Step S1023: Calling a terminal operating system function to extract characters in a screen coordinate range of the coverage area of the finder frame from a character buffer displayed on the terminal screen;

Step S1024, the characters in the screen coordinate range of the extracted framing frame coverage area are enlarged at a predetermined enlargement ratio;

Step S1025: Display the enlarged characters in the imaging screen.

Specifically, as shown in FIG. 10, FIG. 10 is another enlarged display method of the content of the finder frame on the imaging screen in the embodiment. In this method, after the original characters in the finder frame are extracted, the font is enlarged and then displayed on the imaging screen. First, the magnifying glass system calls the terminal operating system function to extract the characters in the screen coordinate range of the framing frame coverage area from the terminal screen display character buffer. When the framing area is a rectangle, the coordinates of the screen area corresponding to the area are (right, bottom), and (left, top) is the coordinate of the upper left corner of the rectangular area i or. (right, bottom) is the coordinates of the lower right corner. The magnifying glass system calls the terminal operating system function, extracts characters from the display character buffer corresponding to the rectangular area on the screen, and copies the extracted characters into the memory, and then displays the characters in the image display screen according to the enlarged font, and You can select, copy, etc. any character in the imaging screen.

In addition, in a specific implementation process, the frame of the framing frame and the imaging screen may be displayed with a predetermined width and transparency; the original display content of the occluded screen corresponding to the area covered by the finder frame and/or the imaging screen The outline is blurred with a preset transparency.

Specifically, as shown in FIG. 11 and FIG. 12, FIG. 11 and FIG. 12 are schematic diagrams showing the semi-transparent blur display of the original content of the finder frame and the imaging screen coverage area screen in the embodiment. The area in the frame of the finder frame is the content to be enlarged that is of interest to the user, and the original display content of the screen corresponding to the area covered by the finder frame and the imaging screen, and the corresponding pixel is image-smoothed and pre-set through the image. The brightness display allows the user to see the enlarged content displayed on the imaging screen while viewing the approximate outline of the original content of the screen covered by the finder frame and the imaging screen.

In addition, as shown in FIG. 13, FIG. 13 is a schematic diagram showing a display mode in which the frame of the hand-held terminal screen magnifying glass system only displays the frame in one embodiment of the present invention. At this time, the original content of the screen that is blocked after the frame is not displayed, and the original content of the screen that is blocked after the imaging screen is still blurred.
